We're dividing 475446 by 728 
The aim is to understand the frequency of 728 in 475446.

Let's proceed to step 1:
The number 728 fits into 4 0 times, leaving a remainder of 4.
Use 0 as the next digit of our solution. 
Result so far: 0.0
Subtracting 0 from 4 leaves us with 4.
Append the next digit (7) from the dividend to 4 and continue with: 47 / 728

Advancing to step 2:
When dividing 47 by 728, we get 0 with a remainder of 47.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtract 0 from 47 to get 47.
Take the next digit (5) from the dividend and append it to 47, then repeat: 475 / 728

Going ahead to step 3:
728 goes into 475 0 times with a remainder of 475.
Write down 0 as next digit of the result. 
Result so far: 0.0
The remainder is 475 after subtracting 0 from 475.
Include the next digit (4) from the dividend after 475, then repeat: 4754 / 728

Going ahead to step 4:
The number 728 fits into 4754 6 times, leaving a remainder of 386.
Record the quotient 6 as the next digit in the result. 
Result so far: 6.0
Subtract 4368 from 4754 to get 386.
Bring next digit (4) of the dividend behind the 386 and repeat the process: 3864 / 728

On to step 5:
The number 728 fits into 3864 5 times, leaving a remainder of 224.
Use 5 as the next digit of our solution. 
Result so far: 65.0
Subtracting 3640 from 3864 leaves us with 224.
Take the next digit (6) from the dividend and append it to 224, then repeat: 2246 / 728

On to step 6:
The number 728 fits into 2246 3 times, leaving a remainder of 62.
Use 3 as the next digit of our solution. 
Result so far: 653.0
Subtract 2184 from 2246 to get 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Moving on to step 7:
When dividing 620 by 728, we get 0 with a remainder of 620.
Record the quotient 0 as the next digit in the result. 
Result so far: 653.0
If we subtract 0 from 620, we get 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6200, and continue the process.

Let's proceed to step 8:
The number 728 fits into 6200 8 times, leaving a remainder of 376.
Record the quotient 8 as the next digit in the result. 
Result so far: 653.08
Subtract 5824 from 6200 to get 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

Step 9:
3760 divided by 728 is 5 with a remainder of 120.
Write down 5 as next digit of the result. 
Result so far: 653.085
If we subtract 3640 from 3760, we get 120.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

On to step 10:
1200 divided by 728 is 1 with a remainder of 472.
Write down 1 as next digit of the result. 
Result so far: 653.0851
Subtract 728 from 1200 to get 472.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4720, and continue the process.

Advancing to step 11:
If we divide 4720 by 728, we get 6 and a remainder of 352.
The number 6 becomes the next digit in our result. 
Result so far: 653.08516
If we take 4368 away from 4720, we end up with 352.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3520, and continue the process.

On to step 12:
When dividing 3520 by 728, we get 4 with a remainder of 608.
The next digit of our result is 4. 
Result so far: 653.085164
If we take 2912 away from 3520, we end up with 608.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6080, and continue the process.

On to step 13:
728 can be fit into 6080 8 times, resulting in a remainder of 256.
Write down 8 as next digit of the result. 
Result so far: 653.0851648
The remainder is 256 after subtracting 5824 from 6080.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2560, and continue the process.

On to step 14:
728 goes into 2560 3 times with a remainder of 376.
Use 3 as the next digit of our solution. 
Result so far: 653.08516483
Deduct 2184 from 2560 and we're left with 376.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3760, and continue the process.

The quotient of the division is 653.08516483, and the remainder is 3.76e-07.
